unlink() problem

I'm having a problem with unlink(). I've scanned the FAQ and searched some
in the newsgroup archives for information about the following problem. I
did find a post (see
http://sources.redhat.com/ml/cygwin/2001-05/msg01095.html ) but no apparent
resolution.
$ touch asdf
$ perl -i -pe 1 asdf
Can't do inplace edit on asdf: Permission denied.
What perl is doing is equivalent to:
$ perl -e '
open A, "< asdf" or die "one $!"; # open asdf for read
unlink "asdf";
open B, "> asdf" or die "two $!"; # open asdf for write
while (<A>) { print B } # copy from A to B
'
two Permission denied at -e line 4.
The problem: after the unlink(), I can't open the same filename for write
as I can on unix. If I pause the program after unlinking asdf, it is still
there and can be seen by ls, but can't be read by ls -l.
Is there a workaround for this behavior? Is it considered a bug or is it
just a quirk of the cygwin implementation of trying to implement unix
filesystem semantics on top of windows?
